1. Clarify The Goals Of The Mailing
For example:
- Increase the size of the congregation
- Invitation to attend Holiday Services (Easter or Christmas)
- Fund Raising 
- Recruitment for Special Ministries
- Promote Church School or Child Care 
- Vacation Bible School

2. Putting Together The Best Mailing List
USPS Mail Carrier Routes are the least expensive mailing lists and can be mailed at the lowest postage rates. Carrier route maps are available so that specific neighborhoods can be targeted. 
You can also purchase a targeted list by religious affiliation, age and income, education levels, ethnicity and more.

3. Use Full Color Postcards With Lots Of Photos
It’s true, a picture is worth a 1000 words, or more! Include a photo of the exterior of the church so the recipient will make a visual connection. Feature members of the congregation in church and at social events. You get the idea. 

4. Use Direct Mail To Drive Traffic To Your Website
Make sure there is lots of good content about the church and its mission. Don’t disappoint web visitors. Your website doesn’t have to be “Madison Avenue”. It can even have a “home-made” look, but it most deliver on content and be worth the visitor’s time.

5. Feature The Pastor
A photo, a biography and sermon excerpts can make an invitation to new congregants personal.

6. Appeal To Everyone
List all of the special ministries, youth, choir, seniors and other groups. 

7. Use A Social Lure
People love to be part of a community. The social aspect of Church membership should be promoted. Try a headline like this one: “MEET OTHER FAMILIES THAT SHARE YOUR VALUES!”
